provements in Electrical Connectors, of

which the following is a specification, the

principle of the invention being herein explained and the best mode in which I have contemplated applying that principle. so as to distinguish it from other inventions.

My invention relates to means for providing a housed or protected connection for the ends of wires of an electrical circuit, and particularly for use as applied to the connection of the circuit wires of electrically operated sad irons, soldering irons and the like with the cord-wires. The object of the invention is to provide means of the above-described character which are simple in construction and efficientin operation.

The said invention consists of means hereinafter described and particularly pointed out in the claim.

The annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means. however,constituting but one of various mechanical forms in which the prin ciple of the invention maybe applied.

.ln said annexed drawing:

Figure 1 represents thehandle of an electrically operated soldering iron partly in axial section and partly in elevation, to which my invention has been applied.

Figure 2 represents a view similar to that of Figure 1 but viewed from a plane at right angles to that from which Figure 1 is viewed.

Figure 3 represents a perspective view of the main or body portion of the connector.

Figure 4. represents an elevation of said body portion viewed from the same direction as is Figure 1. v I 1 Figure @i represents a top plan.

Figure 41-" represents a bottom plan of said main portion.

Figure 5 represents an elevation of the body portion viewed from the same direction as in Figure 2.

Figures 6 and 7 represent elevational views of the closure member and Figure 8 a top plan of the latter.

The illustrated embodiment of my invention comprises a main or body portion 1 of general cylindrical contour and having a reduced end portion 2 also cylindrical. adapted to fit in, in this particular instance. the metallictubular member 3 of the handle of an electrical soldering iron or the like. This main or body portion is provided with a recess 4 bounded by a plane parallel with. the cylindrical axis of the body portion and by an end plane 5 preferably right angular with respect to said axis. The bottom of this recess is intersected by two curved grooves 6, 6. which are adapted to receive the lead wires 7. 7, of the electrical device. The inner ends of these grooves register respectively with two conduits 8, 8 passing through the unrecessed end of the body portion. The opposite ends of these grooves are enlarged as at 9 to acconnnodate the insulation of the main or supply wires 10, 10. as shown in Figure 1. The grooves are each formed with a curved offset portion 6 The recess above referred to is adapted to be closed by a closure member 11. Figures 6 and 7, of a form such will complete the cylindrical contour of the connector. The inner or flat surface of the closure'memberis provided with complementary grooves 12 registering with the grooves 6 and forming inconjunction therejwith continuations of the conduits 8. The middle portion of this closure member is provided with a bore 13 registering with a bore 14 formed in the main or body portion. A suitable screw may be passed through this bore and secured by means of a suitable nut,

so as to fix the closure member in place. The outer end of the bore 14 is preferably countersunk as at 15. Figure 5 so as to receive the nut and the outer end of the bore 13 is also countersunk as at 16. to receive the head of the screw, as will be understood and as is clearly shown in Figure 2. The stripped ends of the supply wires are sol dered or otherwise connected, as at 17 Figure 1 with the ends at the lead wires 7. The offsetportion 6 of the grooves prevent the wires from being longitudinally displaced as will be understood. a

Having fully described my invention, what I claim and desire to secure by Letters Patent is:

A connection protector for electrical apparatus comprising a main body portion rabbetted to form a flat surface parallel with the axis of the member and terminating in a shoulder perpendicular to said axis; u re movable closure memher adapted to fit in the recess formed by said two slju'faces, said main and closure members together forming a complete protector of cylindrical. contour; the opposing faces of the body and closure n'leinbers being provided with longitudinal registering grooves adapted to receive lead irires; that part of the body portion beyond the shoulder being pierced by conduits in 10 alinenient with said grooves to receive the conductor terminals of said apparatus; and means for removably securing said closure in place.
